To all whom it may concern:

Be it known that T, CARL A. LOHMAN, a citizen of the United States, andresident of the city of Seattle, county of King, and State ofWashington, have invented certain new and useful Improvements inLumber-.

' Bundling Frames, of which the following is a specification.

My invention relates to frames or like devices which are designed tobind and hold amass. of lumber into a compact bundle for convenience inhandling the sameand more particularly for use in binding together 1:lumber'preparatory to drying the same in a kiln.

. The object of my invention is to provide a bundle binding mechanismwhich may be conveniently used and which will securely hold the bundleof lumber together while it is being dried in the kiln, and also toprovide a mechanism of this sort which-will automatically tightenup uponthe bundle as the materialshrinks in drying.

The features of novelty of my invention will be herein described andthen particularly pointed out in the claims.

Tn the accompanying drawings I have shown my invention in the form'ofconstrucbeing in the position in which it is placed of the frame,

tion which is now most preferred by me.

Figure 1 V is an end view *ofa bundle showingmy device applied thereto,the same while inthe kiln.

Fig. 3 is a section taken lengthwise the frame 1 of Fig. 1, showing themanner of detachably securing the bar 3 thereto.

Fig. 4 is a face view of the same corner Y Fig. 5 is a cross sectionthrough the bars of the main and of the'tightening frame.

completed andbefore placing'in the kiln.

Tn'the planof operation under which my in the kiln. The lumber is thusplaced in the kiln in large quantities and takenout in similarquantities; Soffaras it is-conven lent to do so, it is desirable thatthe lumber for forming these bundles be sorted as to l ngthgscthatattthe lum er n any one and a binding frame.

of one of the" bundle be of the same length. My device is, however, notlimited to use under these conditions, although these conditions aresuch as are preferred for best results.

Inbuilding these piles I prefer to use not less than three bindingframes for any one pile, unless this pile is of very. short stock. Iprefer that these be placed as is indicated in Fig. 6, with a frameclose to each end of the bundle and one or more intermediate the 7 ends,the number depending upon the length of the stock.

"The binding frames consist of what may be called a main orbundle-encircling frame The bundle-encircling-frame consists of twoparts which are detachably secured together when in use.

3 and 10, and forms the fourth side of the rectangle.

The ends of these bars 3 and 7 are. secured, respectively, to bars 1 and10, insuch manner that they may be attached and detached therefrom. The.manner of securing the bars 1 and '3 together, which has been herein 4shown, consists in providing the bar 1, which is herein shown as achannel bar, with upstanding lugs 12, herein shown as composed of shortsections of angle bar, which are riveted in place between the flanges ofthe channel 1. These are provided each with a hole for the reception ofa bolt 13, which bolt projects beyond the end of the bar 1 and isintended to pass through a hole. in the outer flange of the bar 3. Theinner flange of the bar 3 is cut away for a distance equal to the widthof the bar 1, thus forming a shoulder at 30. The bolt 13 is threaded asufiicient distance so that the bar 3 maybe drawn up or adjusted untilthe outer flange contacts 'with the end ofthe bar 1. The tie-rod '2'.

passes through holes in the otherend of the bar 3 and the correspondingend of the bar 10. By removing the nut which secures this a a t e et 1an the nut upon the this case the main frame, 'jections which enter suchend ofthe rod 13, the two bars 3 and 7 may be removed. This is donewhile the bundle is being formed. 7 I V The bundle binding frameconsists of two bars 2 and 20, which are herein shown as composed ofchannels. These bars are secured in .parallel relation with the bars 1and 10 of the bundle-encircling frame, and are secured thereto in suchmanner that they may have a limited movement in a direction diagonal tothe rectangle and the bundle of lumber. This direction is across theangle between the two parts, 2 and 20. The preferred manner of doingthis consists in providing one'of the frames, as the binding frame 2,with diagonally positioned slots 21, and in providing the other frame,in

with pins or proslots and act as guides to compel movement in thedirection desired. This construction is better illustrated in Fig. 5.

The bar 1 is shownas provided with a hoe, through which passes a pin40,which projects from one side of a spacing block 4:.

- This pmis preferably of non-circular out- 1 lhas a like pin 41,

7 placed downward,-or

.Cotter pins 42, or

line, or of some'equivalent, construction by which it is held againstturning. The block projecting from its opposite sidewhich passes throughthe slot 21.

a like expedient, are employedto prevent separationof the bars.

he position of these slots and the guide pins 40 is such that,when oneof the bars, as the bar 2, is exactly opposite the companion bar 10 ofthe frame, the other bar 20 isoff-set laterally inward with relation toits companion bar 1 of the other frame.

In placing the frames for the formation of the pile of lumber, the bars2 and 10 are so as to have the lumber piled thereon. This position wouldbe that in which the right hand side of the device, as shown in Fig. 1,would be down. In thlSIPOSllllOllf the bar 20 of the tightening frame isoff-set inwardly from the bar 1 of the encircling-frame. In thisposition of the parts, one side and the top of the pile are open, thebars 3 and 7 of the encirclingframe havingbeen removed. For conveniencein piling, siblydollies 5,

are preferably employed, so

. .that after the pile has been formedit may be conveniently moved toany point desired by removing the blocks 6.

Inplaoing thebundle in the dr jiai 'a is turned over intothe positionshown in Fig.

What I claim as my invention is:

1. A bundling device for lumber comprising a bundle encircling frame, abundle clamping frame containing two bars secured by their ends to makean angular frame adapted to engage two adjacent sides of the bundle, oneof said frames having diagonal slots and the other members sliding insaid slots, whereby the frames may have a limited relative movementdiagonally of the frames.

2. A bundling frame for lumber comprising a bundle encircling framecontaining two bars secured by their ends in right angular relation, andtwo other bars secured together in like relation, means for detachablysecuring said pairs of bars together to form a rectangle, said securingmeans providing for a limited adjustment in the size of the rectangle, abundle clamping frame comprising two bars with their ends securedtogether in rectangular relation and means securing said clamping frameupon the other frame to permit diagonal relative movement between them.7

3. A bundling frame for lumber comprising a bundle encircling framecontaining two bars secured by their ends in right angular relation, andtwo other bars secured together in like relation, means for detachablysecuring said pairs of bars together to form a rectangle, said securingmeans providing for a limited adjustment in the size of the rectangle, abundle clamping bar secured in parallel relation with one of the bars ofsaid rectangular frame, and means actuated by the weight of the lumberto bind said clamping bar against the pile of lumber.

- 4:. A bundling frame for lumber comprising a bundle encircling framecontaining two'ba'rs secured by their ends in right angular-relation,and two other bars'secured together in like relation, means for detach-,ably securing said pairs of bars together to forma rectangle, saidsecuring means prov-viding for a limited adjustment in the size I oftherectangle, a bundle clamping frame having two bars adapted to engageadjacent s des of the bundle inwardly ofthe inner of the other frame,the bars of said two frames being secured ,to

gether by means permitting diagonal relative movement between the two.

5. A bundling frame for lumber comprising a bundle encircling framehaving two bars fiXed together by their ends in right angular relation,a bar forming a third side of the rectangle and secured by one end to anend of one of the other bars by a threaded member to permit adjustmentand disengagement, and a tie rod connecting bars to form the fourth sideof the rectangle, a

clamping frame composed of two bars and means securing said bars inparallel relation to the two first named bars and permitting relativemovement diagonally of the rectangle.
